There was breaking news at Affalterbach, Germany ahead of the Geneva Motor Show, that the 2011 S63 AMG will have the company’s all-new 5.5-liter bi-turbo V8 engine, as well as the SpeedShift MCT seven-speed gearbox.
Even though its power compared to the ousted 6.2-liter engine, the M 157 produces 544 horsepower in ‘standard’ mode and 571 with the optional performance package. Despite the change in engine size, the big sedan’s S63 mark will remain.
MB chairman of the board Volker Mornhinweg has also confirmed that the U.S. market will indeed receive technology despite the fact that its efficiency gains are not fully accepted by the EPA’s fuel economy investigation technique. The fuel economy measures are expected to pay dividends in city traffic, which is vital because cities like New York and Los Angeles are important AMG markets.
Despite offering an upsetting show, the S63 is proposed to cut fuel consumption by a surprising 25 percent, due to a “Controlled Efficiency” program, that among other things, directs the transmission to always start in second gear, shift up quickly and remain in higher gears whenever feasible. In addition, the Intelligent Generator Management System installed in the E63 is also used to direct kinetic energy back into the battery. Despite all that the powerful engine will register an impressive 23.5 miles-per U.S. gallon.
The standard S63 is capable of achieving 155 mile-per-hour top speed, while with the performance pack, top speed is supposed to be 186 mph. The new fully loaded and equipped car with state of the art piece of equipment is expected to go on sale in the second half of the year. The 5.5-liter engine is expected to replace the 6.2-liter in other AMG offerings over the next several years. The car spells class and unbeatable luxury and safety standards reserved for the elite.
